Nemesia plant named ‘KLENH10726’

ABSTRACT

A new variety of  Nemesia  named ‘KLENH10726’ particularly characterized by large, violet-colored flowers, good flower performance, and good branching, is disclosed.

Genus and species: Nemesia hybrida.

Variety denomination: ‘KLENH10726’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Nemesia, botanically known as Nemesia hybrida, and hereinafter referred to by the variety name ‘KLENH10726’. This new Nemesia variety was discovered in June 2005 in Stuttgart, Germany and originated from an open pollination between the proprietary female parent ‘SB1’ and an unknown male parent. A single plant selection was subsequently chosen for further evaluation and asexual propagation.

The new variety was first propagated via vegetative cuttings and in-vitro propagation in May 2006 in Stuttgart, Germany and has been asexually reproduced repeatedly by vegetative cuttings in Stuttgart, Germany for over five generations. ‘KLENH10726’ has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety were applied for in Canada on Mar. 30, 2010. ‘KLENH10726’ has not been made publicly available more than one year prior to filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in a greenhouse in hanging baskets.

-   -   1. Large, violet-colored flowers;     -   2. Good flower performance; and     -   3. Good branching.

DESCRIPTION OF THE PHOTOGRAPH

This new Nemesia plant is illustrated by the accompanying photograph which shows inflorescences and foliage of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph was taken in Summer 2010 of a plant about 27 weeks old and grown from rooted cuttings in 15 centimeter pots in a greenhouse in hanging baskets under normal horticultural practices.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘KLENH10726’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. The plant history was taken in the Summer of 2010 on 27-week old plants in 15 centimeter pots in a greenhouse in hanging baskets. The plants were pinched once at 10 weeks. The color readings were determined under natural light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), Fifth Edition (2007).
